GRBOX GRBOX : Gamma-Ray Burst Online Index

[report errors/bugs]
v 0.6 (BETA)

One objective of this website is to be as simple and intuitive as possible, and the most effective way to become familiar with its use is to simply experiment. Nevertheless, certain features are not obvious or may require additional explanation, so a brief 'manual' is provided below.

General Information

Note that only a small amount of the information stored in the database is displayed by default. To access most of the sorting and display options, use the primary table controls - scroll all the way down to the bottom of the page access them.

Almost all text has mouseover information and will bring up the reference when clicked. In addition to providing proper attribution, this can be useful in order to to double-check that the information was entered correctly.

Available Information

The user may elect to display any or all of the following categories of information as columns.

External Resource Links

The GRBOX table can serve as a useful interface for other websites, avoiding the chore of re-entering positional or other information. You may opt to display a large number of external links for each burst:

In addition, you can choose to display a finding chart from several different potential sources:

The SDSS link appears only if the GRB is "approximately" in DR5. The estimation of this is very artificial and misses some SDSS fields and includes some bursts that are not in SDSS. This will be done more exactly in the future.

Some other links are also available:


All of the numerical fields also allow you to sort by that column. You can either select a sort radio button or simply click on the title at the top of the column to sort.

To change the sort direction, check or uncheck the Reverse box. Or, clicking the column title a second time after that column is already sorted reverses the sort direction.

Unknown or absent values are generally treated as zero for the purpose of sorting.

Note that the GRB column actually sorts by UT, so bursts are not always ordered A, B, C the way you might expect.


Always displaying all bursts is very unwieldly. By default, the site only brings up bursts for 2007, allowing you to select different years using the shortcut quick-filter links at top. However, you can choose different filter criteria using any numerical field.

To do this, enter a range in the Start and End boxes below 'Data Options' at the bottom of the page. You can enter only a Start or only an End and it will behave the way you expect, using only a maximum or only a minimum, respectively.

Mouse over the title for more information on filtering by specific fields, as they generally assume values in specific units. Some fields allow the following:

Text Output

You can export much of the data in the table to other formats. At the bottom of the table is a series of links that, when clicked, will print the displayed table in the specified format. (Note that if you have changed options in the fields since the table was displayed those will not be reflected unless you Resubmit Query first.

The options in which to save are:

Non-information columns (links), as well as some information columns (such as Greiner X/O/R) will not display in text files.
